Applcationled December. 30, 1925. Serial No. 78316.

The present application relates to check or coin controlled or operatedmachines or devices. y

Among the objects ofthe-invention is to provide meansV by. whichoperation of such machinesl .or devices with spuriousV checks* or coinscan bereadily detected' although the spurious .check'orZ coin mayhave'the correct shape; size and weight.;

Another object is means by .which 'eXamination may be made ofthe lastcheck/on which mechanism lwill exhibit. to' view.

through asuitable window the last several checks used vfor operationbefore passing them on to the depository.

Reference shouldbe made to' the acconr, panying drawings,l in which:-'

The fdrmofdevic'e chosen for the purpose vof illustration anddescription is one adapt# ed to use with a 'Well known coin or;checkoperated machine and a sufficient portion of..

the latter is shown to indicate thekmechanism usedi-n operating "thedevice.l It is to be understood, however, that the invention is notllimited touse with such machines but may be :adapted withoutmateria-lchange to other Amachines thanfthat shown.

Inthe drawings, the device is shownx as consisting of -a Arectangularvframe or tray 10, divided, in its upper portion by alongitudinall-partition '11, into two channels connecting at their lowerends, there I being. a diagonal partition 12, arrangedV to cause checksfromthe right hand channel to pass into the bottom ofthe left handchannel A "The left handI channel -i-s provided With-a longitudinal`slot 15, through Whichextend `*the fingers 16 ofa conveyor or elevator(to .be described-)which raises the checks from the bottom of-thischannel and: finally drops them through the opening-between bridgeQ piece 17 and the floor-of the channel .into aschute extending to asuitable receiver or deposltory.

lhe back ofthewt-ray 10 is provided With. suitable means 20 by-whichiti-may be secured to themachine lproperrfand the sides" are providedwith channel members- 21 adapted to 4permit coveringdthe tray .with

. a glass cover plate EZQsoathat checksilnthe tray are exposed tooutside view, .it lbeing understood that thefwhole machine and tray willbe suitably Vcovered. except-for the window thus formed.

As mentioned above, the fingers .16 formt parts of a conveyor -for.elevating the checks from the lower -end of the tray .to .the/topVthereof. This conveyor V.is .shown best inA n'. l# igsi` to o, and, inthe present..instance,.con

sists ofthe-three fingers 16 oarried-.pivotally as at 27 on` abar.25.slidably:.mounted.onlthe baclrof tray v1() .insuit-able guidesQ,.The

lingers are. held elevated or. active `position by connectmgfthem.-withspringsY 2.8 un- 5 der slight tension, causing. them to press up againsttheunderside of the-glass `but per` mitti-i'ig-them to bevdepressedtopass underv a check.

Bar 25 is connected` at its lowerv end to a spring- 30 which :in tur-nis .connected to the operatin'glever of the machine and is adapted topull -down the bar Awhen the saidlever-.is operated. .-However,when-said leverl is moved *withouttlie insertion of -a suitable check inthe` proper place, fthebar 25 is held against movement by means of aspring-pressed into notch 32. Furthen-lthe elevator isfreturned-upwardlyhy means of the bar 33H34 connected parallel. tospring 30 andthe same parts,l this bar being madeextensible tofpermitlthe movement ofits lower connection 'Without operation of* the elevator.

In order to retain the checks in elevated intermediate positionftheadditional spring ingers 35 are arrangedxntoextend.' through the'trayfloorjin slots-3G extending laterally from slot 15.-A These lingers 35are'p'ivoted on the backof the'trayf'at? 'and located sov as to retainthe checks elevated by the lower two lingers 16.., 1

ln addition-to its functionas a-pawl for retaining bar 25 in velevatedposition, vpaw'l pawl 31'l 3l carries a finger 4() extending through anopening 41 in the floor of the tray in the right channel. `When the pawlreleases bar 25 and the latter drops, the finger 40 extends far enoughinto the tray to hold the incoming check and prevent its passing intothe bottom of the elevator' channel until the elevator has liftedtherefrom a previously used check. TWhen the elevator' has risen nearlyto the top, the bar 25 lifts the pawl and finger 40 so as to retract thelatter and allow the last check used to drop into the bottom of theelevator channel.

The device, therefore, as illustrated, will present to view the lastfour checks used to operate the machine and thereby permit an attendantto detect the use of improper checks to within several operations of themachine.

The device as applied to a well known form of check controlled machineis shown in Fig. l.

In this figure, the device is shown as a whole at 50 secured to themachine, which latter comprises a frame 51 carrying the usual mechanism.This mechanism is ladapted to be set in motion by depressing the lever52 and thus storing energy in a spring (not shown), which energy isreleased to the movable parts, the release being controlled by asuitable governor, such as the air fan 52, so that the parts return torest position more or less slowly.

Nhen the lever 52 is depressed, without insertion of a coin or check inthe receiver 53, lever 54 is moved toward the left and through its armlifts bar 5G and with it means (not shown) carried by the latter toprevent actuation of the mechanism. However, when the lever 52 isdepressed, after insertion of a check, lever 54 is prevented by thecheck from movement and with it bar 56 is prevented from movement untilafter the mechanism has begun to be actuated. TLlnder these conditions,bar 56 continues to rise till near the end of the stroke of lever 52when it is given a quick upward movement.

In this quick upward movement the bar 56 through a stud 57 gives lever58 a quick movement and the latter in turn deprcsses the arm 59 carriedby pawl 31. lWhen arm 59 is depressed it releases pawl 3l from notch 32in the elevator bar 25.

In the meantime, the depression of lever 52 has caused the mechanism ofthe machine to operate lever and has thereby extended spring 30, so thatwhen the pawl 3l releases the bar 25, the latter is immediately drawn toits lowest position, `When the conveyor is in this position, pawl 3l canand does` move forward to project finger 40 through opening 41 where itis in the path of the check just used to operate the machine.

As the machine mechanism returns slowly to rest, the conveyor bar 25slowly raises and lifts the several preceding checks until at last thefinger 40 is withdrawn and the last check drops to the lowest positionin the left hand channel of the tray.

While the form of device shown in especially adapted to be used with thetype of check controlled machine shown, it permits of broaderapplication and it is contemplated to use it with any check controlledor operated mechanism for the purpose of aiding in the detection of theuse of improper checks or coins.

p Having now described the invention and the preferred form ofembodiment thereof, it is to be understood that said invent-ion is notto be limited to the exact. details shown and described but only by thescope of the claims which follow.
